I had sex 5 days ago and since then i have a terrible pressured feeling in my lower abdomen, and every so often i feel like my period is about to come soon..but it's not and i haven't had any spotting.

Also, I have this weird growth inside my vagina (about 3-4inches up) that I've had for a good 5 years but I've never had any real problems with (I could have it longer but I hadn't really ventured too far up that way until then). It's not really attached to the wall I don't think as I can move a finger 360 degrees around it, and if I touch it I can feel that weird pressure/period feeling.

I had a full abdominal scan last year as the doc thought I might have ovarian cysts because of the pressure feeling but it turns out I have a retroverted uterus, so surely if I had a scan like that, whatever this growth is would show up, would it not??
